The EZ80 full wave rectifier was found in many broadcast receivers and domestic audio equipment.
Suited to the task, at 90 mA maximum current and with a required series resistance of 300 ohms to reduce the initial surge in charging the maximum 50 µF reservoir capacitor, each anode would conduct in turn when connected to either end of a grounded centre tapped mains transformer.
The anodes were set at right angles to one another around the central cathode tube.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 59 mm tall.
